Objective To apply the method of evidence-based medicine to identify the best therapy option for an emergency patient with upper gastrointestinal hemorrhage. Methods According to time and logical sequence of clinical events, a complete decision tree was built after the following steps to find the best treatment: clear decision-making, drawing decision tree graphics, listing the outcome probability, giving appropriate values to the final outcome, calculating and determining the best strategies. Results The performance of endoscopic therapy for the patient with upper gastrointestinal hemorrhage within the first six hours had little effect on the prognosis. Interventional therapy after the failure of endoscopic therapy had less mortality than direct surgical exploration. Conclusion Making clinical decision analyses via drawing the decision tree can help doctors clarify their ideas, get comprehensive views of clinical problems, and ultimately choose the best treatment strategy for patients.
Objective To investigate the cause, treatment, and prognosis of the postpancreaticoduodenectomy hemorrhage (PPH) . Method A total of 779 patients who underwent pancreaticoduodenectomy at Fudan University Shanghai Cancer Center between January 2015 and December 2016 were enrolled, and the data of them were retrospectively analyzed. Results Sixteen patients (PPH group) suffered from PPH and 763 patients didn’t suffered from PPH (non-PPH group) of 779 patients. There was no significant difference in the age, gender, type of disease, operative time, blood loss, and ratio of blood transfusion between the 2 groups (P>0.05), but the incidences of pancreatic fistula and delayed gastric emptying, postoperative drainage time, hospital stay, and mortality were all higher or longer in PPH group compared with non-PPH group (P<0.001). Of the 16 PPH patients, early haemorrhage occurred in 3 patients (including 2 patients with gastrointestinal haemorrhage and 1 patient with intra-abdominal haemorrhage) and delayed haemorrhage occurred in 13 patients (including 6 patients with gastrointestinal haemorrhage and 7 patients with intra-abdominal haemorrhage). All the 3 patients with early haemorrhage were cured by surgery. Of the 13 patients with delayed haemorrhage, 5 patients were cured by radiological intervention, 2 patients were cured by endoscopic hemostasis, and 3 patients were cured by conservative treatment, but 3 patients with sentinel bleeding died after interventional embolization+surgery. Conclusions The mortality of PPH is high. Surgery is optimal to early haemorrhage and radiological intervention is optimal to delayed haemorrhage, including embolization or covered stent implantation. The sentinel bleeding should be given great attention.
Objective To explore whether there is enough clinical evidence to confirm that stereotactic aspiration does more good than harm in patients with cerebral hemorrhage. Method A systematic review of all relevant clinical studies on stereotactic aspiration in the treatment of cerebral hemorrhage. Results Eight randomized controlled trials (RCTs) including 757 patients and 17 nonrandomized controlled studies including 1 766 patients, as well as 20 uncontrolled studies including 1 244 patients were identified . All studies reported positive results regarding the effects. However, the quality of the included studies were generally poor. The main problem was that most trials reported them as a RCT, but no description of the method of randomization. Conclusions Stereotactic aspiration in the treatment of cerebral hemorrhage is promising based on present evidence. However, at present, we can not draw definite conclusion whether the treatment does more good than harm compared with noninvasive medical treatment because of the poor quality of included studies. Therefore, more high quality RCTs are required.
ObjectiveTo observe and analyze the risk factors related to vitreous re-hemorrhage (PVH) after anti-VEGF drugs combined with vitrectomy (PPV) in patients with proliferative diabetic retinopathy (PDR).MethodsRetrospective analysis study. From April 2017 to July 2018, 100 eyes of 87 PDR patients who were diagnosed in Jiaxing Eye Hospital and received anti-VEGF drugs combined with 25G PPV were included in the study. Among them, there were 44 eyes in 38 males and 56 eyes in 49 females. The age ranged from 26 to 83 years, with an average age of 57.72±8.82 years. All patients were type 2 diabetes, with an average duration of diabetes 10.84±6.03 years. All affected eyes were assisted by the same doctor with a non-contact wide-angle lens under the standard three-channel 25G PPV of the flat part of the ciliary body. Five to 7 days before the operation, intravitreal injection of ranibizumab or conbercept 0.05 ml (10 mg/ml) was performed. The incidence of PVH was observed. The age of PVH patients, duration of diabetes, vision before operation, average fasting blood glucose and average postprandial blood glucose before operation, systolic blood pressure and diastolic blood pressure before surgery, laser treatment before surgery, lens removal during operation, intraocular filling during operation, retinal laser points during operation, and fundus lesions during operation (hyperplasia film, Retinal hemorrhage, vascular occlusion, proliferative retinal traction, retinal hiatus, retinal detachment, exudation, neovascularization) were analyzed to find out the cause of PVH. Spearman bivariate correlation analysis and binary logistic regression analysis were performed on the data.ResultsOf the 100 eyes of 87 patients, PVH occurred in 17 eyes (17%). There were statistically significant differences in the number of eyes with vascular occlusion and proliferative traction during surgery in patients with and without PVH (χ2=5.741, 8.103; P＜0.05). There was no significant difference in age (t=－1.364), duration of diabetes (t=0.538), preoperative vision (t=1.897), preoperative fasting blood glucose level (t=1.938), preoperative postprandial blood glucose level (t=1.508), preoperative systolic blood pressure (t=－0.571), preoperative diastolic blood pressure (t=0.275), whether received laser treatment (χ2=2.678), the number of laser points during operation (t=0.565), whether received lens removal during operation (χ2=0.331), whether found new blood vessels during operation (χ2=2.741) and whether received intraocular filling during operation (χ2=0.060) between the patients with and without PVH (P＞0.05). Spearman's bivariate correlation analysis showed that patients with low vision, poor control of fasting blood glucose levels, vascular occlusion and proliferative retinal traction during the operation were related risk factors for PVH (rs=0.208, 0.229, 0.240, 0.285; P＜0.05). Binary logistic regression analysis showed that fundus vascular occlusion and hyperplastic retinal traction may be independent risk factors for PVH during surgery (OR=5.175, 13.915; P＜0.05).ConclusionFundus vascular occlusion and retinal traction caused by fibrovascular membrane hyperplasia in PPV may be independent risk factors for PVH in patients with PDR after anti-VEGF drugs combined with PPV.
Objective To observe the fundus characteristics and associated factors of retinal hemorrhage (RH) in newborns. Methods A total of 293 healthy newborns (586 eyes) were enrolled in this study. A digital wide-angle retinal imaging device (RetCam Ⅲ) was used to examine the subjects at about 2 days after birth (2.7plusmn;0.9) days. The images of posterior pole, temporal quadrant, superior quadrant, nasal quadrant and inferior quadrant of the fundus of each eye were taken sequentially. Every newborn completed the examination and the mean duration of the procedure was (2.62plusmn;0.55) minutes. Newborns with RH were reexamined after one month. RH was classified according to the location and size of the hemorrhages based on guidelines in the literature. The location and degree of RH was determined in each newborn. The incidence of RH by gender, parity, birth weight, maternal age and delivery method was compared and analyzed. Results RH was present in 87 eyes (14.8%) of 58 newborns (19.8%) and of the 58 newborns with RH, half (29 eyes) had hemorrhages in both eyes, and half (29 eyes) had hemorrhages in only one eye. The site of the hemorrhage was all on the superficial retina. Of the 87 eyes with RH, 72 eyes (82.8%) had hemorrhage in zone Ⅰ, 86 eyes (98.9%) had hemorrhage in zone Ⅱ, and 36 eyes (41.4%) had hemorrhage in zone Ⅲ. Thirty-eight eyes (43.7%) had hemorrhage in zone Ⅰand Ⅱ. Three eyes (3.4%) had hemorrhage in zone Ⅱ and Ⅲ. Thirtythree eyes (37.9%) had hemorrhage in zone Ⅰ, Ⅱ and Ⅲ. One eye (0.4%) had hemorrhage in zoneⅠonly. Twelve eyes (13.8%) had hemorrhage in zone Ⅱ only. None had hemorrhage in zone Ⅲ only. The severity of RH was grade Ⅰ in 13 of 87 eyes (14.9%), grade Ⅱ in 33 of 87eyes (37.9%), and grade Ⅲ in 41 of 87 eyes (47.1%). Fourteen of 58 newborns with RH (24.1%) were lost to follow-up. Forty-four of 58 newborns with RH (75.9%) were reexamined one month after birth and all the RH disappeared entirely. There were no statistically significant differences among the incidences of RH of the different gender (chi;2=0.018,P=0.893), parity（chi;2=0.772,P=0.380）, birth weight（chi;2=1.611,P=0.447）and maternal age (chi;2=0.915,P=0.339). The incidence of RH was higher for vaginal delivery than that for cesarean section delivery (chi;2=3.073,P＜0.05). Conclusions The RH in newborn is located in the superficial retina, mostly located in zone Ⅰor zone Ⅱ, and resolves itself within one month after birth. The RH in newborns is related to the mode of delivery, but not related to gender, parity, birth weight or maternal age.
Objective To observe and analyze the causes and prognosis of postoperative vitreous hemorrhage (PVH) after vitrectomy for proliferative diabetic retinopathy (PDR). Methods A total of 160 PDR patients (171 eyes) were enrolled in this retrospective study. There were 85 males and 75 females. The patients aged from 33 to 73 years, with the mean age of (56.40±8.97) years. All the patients were performed 25G pars plana vitrectomy by the same doctor. Fibrovascular membrane peeling and panretinal photocoagulation were performed during the operation. Combined phacoemulsification was performed in one hundred and five patients. Vitreous tamponade was used at the end of surgery, including silicone oil (43 eyes), C3F8 (63 eyes), air or fluid (65 eyes). The follow-up ranged from 6 to 22 months, with the mean follow-up of (9.34±6.97) months. The features of PVH were observed. The difference of age, HbA1c, creatinine level, the severity of the fundus lesions, whether received treatment of anti-vascular endothelial growth factor (VEGF), whether received combined cataract phacoemulsification were analyzed to find out the cause and prognosis of PVH. Results The corrected vision of all the patients after the primary PPV at the latest follow up was finger counting/1 meter. PVH occurred in 15 eyes of 15 patients, the incidence was 8.77%. The PVH occurred 2 weeks to 6 months after surgery. There were significant difference in age (t=2.551), proportion with tractional retinal detachment (χ2=7.431), progressive fibrovascular proliferation (χ2=4.987) and using anti-VEGF (χ2=9.742) between the patients with and without PVH (P＜0.05). There was no significant difference in HbA1c (t=0.501), creatinine level (t=1.529), and the proportion of cataract phacoemulsification (χ2=0.452) between the patients with and without PVH (P＞0.05). During follow-up, neovascularization of iris (NVI) occurred in 1 eye and neovascular glaucoma (NVG) occurred in 4 eyes. Seven eyes underwent reoperation, 7 eyes were spontaneous recovered, 1 eye with NVG give up treatment. Fibrovascular membrane was the major cause of recurrent hemorrhage. At the end of follow-up, hemorrhage was absorbed in all the 14 eyes which were treated, 12 eyes had same visual acuity compared to that before postoperative hemorrhage, 2 eyes with NVG had decreased vision. There was significant difference in the corrected vision between the patients with and without NVI or NVG (P=0.022). Conclusions PVH after PPV for PDR is closely related to the severity of diabetic retinopathy, fibrovascular membrane is the major cause of recurrent hemorrhage. NVG is an important factor related to vision acuity prognosis.
ObjectiveTo explore the effects of small dose and low pressure lavage on gastrointestinal hemorrhage induced by acute poisoning. MethodsWe collected the clinical data of all the patients diagnosed as gastrointestinal hemorrhage induced by acute poisoning treated between January 2011 and December 2012. The patients were divided into two groups: control group and treatment group, according to the different treatments they underwent. The control group received traditional treatment only, while the treatment group received small dose and low pressure lavage as well as the traditional treatment. After recording the ages, poisoning dose, pretreatment time, shock and complications, we evaluated the risk of death by calculating ROCKALL scores. ResultsThe differences of ages, sexes, and poisoning dose between these two groups were not significant. However, the death rate in high and middle risk patients of the treatment group was significantly lower than that of the control group (P<0.05). ConclusionThe small dose and low pressure lavage can improve the prognosis of the gastrointestinal hemorrhage induced by acute intoxication.
ObjectiveTo conduct an objective record of stroke patient’s retinal diseases by retinal photography, and analyze the incidence of various retinal diseases between different subtypes of stroke.MethodsFrom June to October 2007, the consecutive cases of stroke admitted to the Department of Neurology, West China Hospital of Sichuan University were prospectively registered. Ischemic stroke patients were classified into different subtypes by the Oxfordshire Community Stroke Project criteria, and intracerebral hemorrhage (ICH) patients were classified based on the clinical manifestation and neuroimaging. We collected other clinical data associated with the incidence of stroke. The retinal abnormalities including retinopathy, arteriovenous nicking and arteriolar narrowing were recorded. Multivariate logistic regression was performed to investigate the relationship between retinal abnormalities and stroke.ResultsThis study included 199 patients with ischemic stroke and 95 patients with ICH. Among the patients with ischemic stroke, 43 (21.6%) had retinopathy, 52 (26.1%) presented with arteriovenous nicking, and 43 (21.6%) developed arteriolar narrowing. Among the patients with ICH, retinopathy occurred in 23 (24.2%), arteriovenous nicking occurred in 14 (14.7%), and arteriolar narrowing occurred in 25 (26.3%). In multivariate analysis, retinopathy was independently associated with partial anterior circulation infarct (PACI) (P=0.029) and anterior ICH (P=0.041).ConclusionsRetinopathy is independently associated with PACI and anterior ICH. Further community-based study with large sample should be conducted to confirm the predictive value of retinal diseases on the incidence of anterior stroke.
PURPOSE:To search for the occult choroidal neovascularization(CNV)of age-related macular degeneration (AMD)with macular hemorrhage using indocyanine green angiography(ICGA). METHODS:FFA and ICGA were performed in a series of 22 cases(24 eyes)of AMD with macular hemorrhage,and the findings of both angiograms were compared each other. RESULTS :ICGA was found to be superior than FFA in evaluating the occult CNV of AMD with hemorrhage owing to the following outstanding findings in this series,i.e,in judging the presence,position,number and range of the occult CNV. CONCLUSION:ICGA is an important technique in diagnosing the subretinal occult CNV in AMD with macular hemorrhage,and useful in selecting therapeutic measures including photocoagulation and surgical treatment. （Chin J Ocul Fundus Dis,1997,13: 146-149）
Objective To investigate the clinical characteristics and the related factors of peripapillary subretinal hemorrhage (PPSRH). Methods The clinical documents of fundus fluorescein angiography (FFA) of 23 patients (23 eyes) with PPSRH were retrospectively analyzed. Results All of the 23 eyes was myopes with middle or slight degree, and the corrected visual acuity was≥1.0. Among the 23 patients, 9 eyes were PPSRH, 13 eyes were PPSRH with disc hemorrhage, and 1 eye was PPSRH with disc and vitreous hemorrhage. All of the PPSRH was localed at the nasal edge of optic disc. Through FFA the hemorrhage showed blocked fluorescence and the optic disc showed nodular hyperfluorescence at the late phase, and nothing abnormal in the unaffected eyes. Conclusion PPSRH might be related to buried optic disc drusen. (Chin J Ocul Fundus Dis, 2002, 18: 96-97)
